Set a feature to prevent versions older that 2.6.20 from loading a
database from which they cannot read the dates. Ideally we would do this
only if the database is written to, but the current persistence design
includes committing back to the database during the load so the net
effect is that the flag would be set anyway.
This allows direct conversion between Scheme numbers and gnc_numeric
without the performance or accuracy penalties arising from using doubles
as an intermediary.
as it doesn't load proper backend.
The cause was that the libdbi-driver path in CMakeLists.txt was wrong
and GNC_DBD_DIR was being set unconditionally in etc/gnucash/environment
with an invalid path.
Sets paths for finding componenents depending on the state of ENABLE_BINRELOC,
GNC_UNINSTALLED, GNC_BUILDDIR and whether any install paths have been set
outside of CMAKE_INSTALL_PREFIX.
GNUInstallDirs changes the name of CMAKE_INSTALL_LIBDIR depending on the
operating system and distro. When CMAKE_INSTALL_PREFIX is /usr,
/usr/local, or any subdirectory of /opt it also changes
CMAKE_INSTALL_FULL_SYSCONFDIR to /etc. An earlier commit by Aaron Laws
mirrors the name of CMAKE_INSTALL_LIBDIR to the build library directory.
It's possible for builders to set any of the install directories
anywhere they please.
Setting any directory outside of CMAKE_INSTALL_PREFIX breaks Binreloc so
the toplevel CMakeLists.txt now detects that and disables Binreloc.
If Binreloc is enabled then all path queries use it to find paths. This
works in the build directory because the gnucash executable and all of
the test programs are in build_directory/bin and LIBDIR, DATADIR, and
SYSCONFDIR can be found in the same root path.
If Binreloc is disabled then in order to build or run programs from the
build directory one must set GNC_UNINSTALLED and set GNC_BUILDDIR to the
absolute path of the build directory. When those are set GNC_BUILDDIR
replaces CMAKE_INSTALL_PREFIX in all paths that are subdirectories of
CMAKE_INSTALL_PREFIX; paths that are not in CMAKE_INSTALL_PREFIX are
appended whole to GNC_BUILDDIR. This process is constent between CMake
and gnc_path_get_foo. GnuCash is unlikely to run from a DESTDIR without
Binreloc.
Only string values should be quoted in queries; in particular NULL
isn't a string value and must not be quoted.
Note that this is a less than perfect solution because it doesn't use
the Database's quoting function and so doesn't escape quotes, linefeeds,
or carriage returns inside the string. That's because the SQL generating
logic is independent of the connection class and can't easily get to it.
Wherin the problem is that MySQL's TIMESTAMP has a date range of
1970-01-01 00:00:01 to 2038-01-19 03:14:07 and is unable to handle
time_t of 0. MySQL's TIMESTAMP also assumes that input is in the server's
timezone and adjusts it to UTC. GnuCash has already done that conversion.
For each subclass, getting rid of GNC_SQL_OBJECT_BACKEND_VERSION which
was a bit misguided.
Also remove the bogus test the skipped loading a table if its version
didn't match GNC_SQL_OBJECT_BACKEND_VERSION which was even more misguided.
glib-compile-resources lists the resource files as absolute paths,
but SET_LOCAL_DIST expects relative paths; the result was that the
tarball code was looking for ${CMAKE_SOURCE_DIR}/${CMAKE_CURRENT_SOURCE_DIR}/foo.
This change strips off ${CMAKE_CURRENT_SOURCE_DIR} from the filenames
before passing them to SET_LOCAL_DIST.
Commit 88b8477 on libdbi calls the error handler if one attempts to run
off the end of a result set. Since we often loop on
dbi_result_next_row() returning 0 this breaks our logic in several
places. This change simply returns from the error handler on a
DB_ERROR_BADIDX allowing the logic to work as before.
I.e., remove the shell invocation and with it the need to set the shebang.
Surprisingly this required some build-system modifications particularly
for cmake in order to correctly set the environment.
There seems to be more than one problem that causes the exception handler ("catch") to
get lost on Windows:
* Throwing from a constructor called from a member function of another object of the same
class. That's fixed here for the GncNumeric string constructor, but there's at least one other
instance I'm still working on in GncNumeric::to_decimal.
* Hidden memory allocation in a stack-allocated object like std::string, std::istringstream,
or boost::smatch: The throw causes the object to go out of scope which calls its destructor
and in that case the catch reference is either lost or never compiled in.
This change ifdefs out the creation of detailed exception messages on Windows to avoid
the destruction of the std::istringstream and its attached std::string, creates a series of
helper functions to ensure that the boost::smatch is in a non-throwing scope, and puts the
computed values directly into the member variables instead of delegating the construction
to a temporary and then copying out the values. The last item is more correct anyway, as
C++ constructor delegation is supposed to happen in the member initialization part rather
than the function body.
With these changes the exceptions from the GncNumeric string constructor are handled
correctly.
gtk-mac-bundler can't access the executable's rpath list so it can't
follow dependencies if they're not in $install_dir/lib from @rpath.
Autotools always sets absolute path install names so this should have no
adverse affects on other Mac builds.
